An administration that goes out of its way to make terrorism sound less dangerous than it really is (i.e. "man-caused disaster") makes the push to sell "global warming" as more dangerous than it really is. Sounds like somebody's starting to feel uncomfortable because the icecaps and Greenland ice sheets aren't melting fast enough. Switching "warming" to "disruption" is like Chicken Little — finally realizing that everybody's catching on — switching to crying "the ground is rising!"
